Abstract (en)
A method is proposed for identifying a chemical substance from a set of output states provided by a chemical sensor array being exposed to the chemical substance. The method comprises steps for selecting from a set of class descriptions for different chemical substances a first class description and one or more further class descriptions, whereby the first class description is related to a first chemical substance and a further class description is related to a further chemical substance, estimating a first likelihood value and one or more further likelihood values, whereby the first likelihood value represents a probability that the set of output states corresponds to the first class description, and a respective further likelihood value represents a probability that the set of output states corresponds to a respective further class description, and determining from the estimated first and further likelihood values the class description with the highest likelihood value. Hereby an estimation of a first and/or further likelihood value combines the likelihood values estimated for at least two subsets of the set of output states corresponding to the first and/or further class description, respectively.
